Fish with a spike. Stab other fish before they stab you and grow from what they drop. 2020.
Stabfish.io is a free eat and grow io game (free-for-all, fast). You start tiny. Everything smaller is food, everything bigger is death. The loop Agar.io invented in 2015, and the food-chain games that grew out of it. It ran when last checked, on 2026-09-16.
The game loads from stabfish.io in a frame. Its own terms, privacy policy, ads and accounts apply inside it, and a save made here is separate from one on stabfish.io. If you already have progress there, open the game on its own site. How the frames work.
